A live updating surf poster.

• Raspberry Pi Zero W with headers $14
• Regular old USB Micro cable and wall plug (you probably have an extra one)
• Female/male jumper wires $2
• 3 micro servos $10
• >2GB flash micro card $2
• Shadow Box (I used 8x10, but it feels a bit small) $32
• Print of your beach picture $2
• Black and white printout of above photo

Total: $46

• Power drill with a variety of bits
• Wire stripper
• Tiny screwdriver
• Computer
• WiFi

I made a beach scene by taking a photo and running it through Adobe Illustrators Image Trace filter, and I'm sure you can make something creative. Try out Inkscape if you want a free image editor.

See ASSEMBLY.md

• Fetches surf data from surfline.com (currently only for Tourmaline Beach)
• Converts that data into signals to adjust the angle on servo controllers
• Runs on a raspberry pi (zero w)

Why? Getting things running with python3 was a pain. For some reason it took 10s+ to get a virtualenv setup with pipenv, so I ditched it in favor of the system python2

• Get your pi
• Install these dependencies:
  • python-requests
  • python-RPI.GPIO
• Hook up your servo wires according to the pin numbers in actuate.py
• Run the script with python main.py to get live data OR python manual.py <surf_height> <water_temp> <surf_quality> to put in your own data

Add this with crontab -e:

0 * * * * cd /home/elliot/code/surf-poster && python main.py >> /home/elliot/logs/surf-poster.log 2>&1
1 0 1 * * mv /home/elliot/logs/surf-poster.log /home/elliot/logs/surf-poster.log.bak && echo -n > /home/elliot/logs/surf-poster.log 2>&1
